Fig. 8 has shown the exploded view of an energy absorption shell 22.This energy absorption shell 22 comprises a shell 108, and it is formed on two parts, to satisfy the seam 110 at a horizontal alignment.Described housing has defined front surface 112 and the rear surface 114 that is against described adjacent separator assembly 14.Each housing 108 has also defined a corresponding top surface 116.Described top surface 116 has defined compressibilty and has strengthened zone 118, has defined in the present embodiment a parallel pleated or ripple (corrugations) 120 arrays.These ripples 120 usually extension are parallel to described front surface 112 and rear surface 114.Described compressibilty strengthens regional 118 and guarantee that if described housing 108 axially compresses, this compression is positioned at zone 118 at first between front surface 112 and rear surface 114.Only by way of example, the length of described housing 108, height and width are approximately 82,57 and 55 centimetres, and can be approximately 11 centimetres at the width in zone 118.Described housing 108 can be with molded the forming of any suitable material, such as straight chain, high density or low density polyethylene (LDPE), for example, a kind of ultraviolet inhibitor.Described housing 108 can comprise any suitable energy absorbing element 109, and the present invention is not limited to any specific arrangement of components.For example, energy absorbing element can be as described in 4352484 the United States Patent (USP) such as the patent No., uses a frangible paper honeycomb material (5 centimetres honeycomb diameter and 5 cm layer thickness) and polyurethane foam.Alternative, described energy absorbing element 109 can be formed by frangible metal beehive body member 11, and each thick 17.8 centimetres, honeycomb diameter are 3.8 centimetres.Described element is preferably dead annealed low carbon steel plate (elements of the element of 0.45 millimeters thick and other three 0.71 millimeters thick) and forms.In the embodiment in figure 1, described (a plurality of) front shell 22 for example is arranged on protuberance compartment 22, can use described paper honeycomb material and described rear compartment, the Steel material that shell 22 adopts as described in can using such as two recess.Yet, should be understood that, be not limited to above-described embodiment at energy absorption shell 22, and any free floating (free-floating) energy absorbing device of enough energy absorption is provided, in described compartment 2, all can use.
In one embodiment, because described shell 22 is frangible, they place in the described compartment 2 with may being difficult to permanent adherence, for example, and the place in described protuberance compartment or recess 4.In addition recess 4 compression and the intussusception in the wings along with protuberance compartment and dividing plate 14 because described shell 22 is designed to collapse, it is preferably, impact and deformation phases between described shell 22 do not keep fixing.Therefore, in one embodiment, described shell 22 places in the compartment 2, comprises described protuberance compartment and described recess 4, to such an extent as to they are not connected with described framework, comprises dividing plate and Crashworthy plate.In the present embodiment, the soffit of described shell 22 rests in the support that places each described compartment 2 simply.For example, described foremost shell 22 can rest on the A-frame 203 of the front surface that is connected to described foremost dividing plate and be connected on the A-frame 201 of protuberance guard shield described in Fig. 1,11 and 13.Described shell 22 does not connect, yet, for the assembly in described protuberance guard shield 24 or other the described protuberance compartments, and be to support at described compartment simply.Similarly, in recess 4, in fact described shell 22 is not connected to described dividing plate 14, Crashworthy plate 16 or guide rail 12, but supported in the described compartment that it defines.In other embodiments, described shell 22 can crisply be connected to described framework by safety pin (shear pins) or similar item, it is designed to can make in crash bump to lose efficacy, and allows described shell 22 mobile in direction backward when described compartment 2 cover superimposition are collapsed.
Embodiment has utilized shell 22 to avoid being connected with described vehicle barrier 10, is conducive to assembling process and maintenance/Renewal process in the follow-up simplification of Vehicular impact.Yet, because in fact the described shell 22 among these embodiment is not connected to described vehicle barrier 10, be possible so during clashing into, shear or break through described shell for described shell.For example, the shell in described protuberance compartment may have mobile in vertical direction tendency.Such movement is partly to alleviate described protuberance compartment by described steel protuberance guard shield 24; be tending towards crushing and curve inwardly towards the center of described protuberance compartment, thereby " controlling (the gripping) " effect at described most important shell 22 front ends is provided.Yet when lacking described retaining device 3, described shell 22 may move during clashing into, rotates or otherwise move up, and may cause the fragmentation of described shell 22, or protrudes on described Crashworthy plate 16.If whole shell 22 no longer is to be completely contained in the compartment 2, only in fact some shell contacts compression shock power, and therefore, only total potential energy of some shell 22 absorbs and is utilized.
Therefore, in this case, described shell 22 is to utilize during Vehicular impact and extra energy must be arranged on other compartments 2(such as, recess 4 by described residue) shell 22 be absorbed.In some cases, under the energy absorption capability of utilizing described (a plurality of) shell, particularly the most important shell 22 that is arranged on described protuberance compartment may cause whole described vehicle barrier 10 can not absorb energy enough or desired amount.That is to say, if most important shell 22 can not absorb the energy of its maximum capacity haply, the described total system efficient that becomes is lower, and the amount of energy of the described vehicle barrier 10 that defines can reduce.Therefore, extra recess must be added in the described vehicle barrier 10, reaching the energy absorption of desired level, thereby causes unnecessary cost and the waste of resource.
According to application, described energy absorption formula vehicle barrier 10 can have the compartment 2 that described framework defines that passes through of varying number.Tell is assembled by a plurality of baffle assemblies 14, Crashworthy plate 16, guide rail and protuberance guard shield 14 with framework.Can be regarded as, in other embodiments, the described framework that defines compartment can be by different module compositions.In the example of Fig. 1, described vehicle barrier comprises three independently 2: one protuberance compartments of compartment and two recess 4.It should be understood, however, that described vehicle barrier 10 is not limited to this, and can comprise plural recess 4, such as, but not limited to, five or more recess 4.For the purpose of this manual, recess 4 can be described as comprising two of a pair of barrier film that vertically separates 14, energy absorption shell 22 and the relative both sides that are arranged on described shell 22 be spaced laterally apart, the part of the described energy absorption formula vehicle barrier 10 of the Crashworthy plate 16 of longitudinal extension.
